ings and is described in the f0 lowing specifi,

Be it known that I, RAYMOND O. CoBURN, a citizen of the United-States, residing at Upper Sandusky, in the county of Wyandot and State of Ohio, have invented a new and usecation.

This invention relates to improvements in that class of inhalers particularly useful for administering anesthetics.

As is well known, anesthetics are preferably administered through the nose; but as some patients are unableto thus take the same it is the ordinary practice-in such cases to employ a ful Inhaler, of which the following is a specifi-' difierent inhaler for the mouth. The use oftwo independent devices, however, is often inconvenient; and one of the objects of the present invention is to provide a structure that is adaptable for use either as'a nasal or oral inhaler, the necessary changes being easily ac- A further object is to provide an inhaler wherein the ex irations" of the 'patient are pro erly allowe to escape from the inhaler, whi e the atmospheric air is excluded during inspirations, the inhaler being adjustable to preclude the escape of the anesthetic agent.

after the patient is under the influence thereof. The preferred embodiment of the invention is illustrated in the accom anying drawcation. An inspection of the claims will show, however, that the'inventionis not limited to the particular structure set forth, but

is open to various changes and modifications. In the embodiment illustrated, Figure 1 is a perspective view of the inhaler. Fig. 2 is a vertical sectional view, therethrough, but showing the lower section moved downwardly, or, in other words, illustrating the inhaler when extended. Fig. 3 is a horizontal sectional view. Fig. 4 is a sectional view taken on the line 4 4 of Fig. 2. Fig. 5 is a detail sectional view through the outlet-nipple. Similar reference-numerals indicate COI'I'G.

sponding parts in all the figures of the drawopen side a lip -receiving recess 9. It is lngs.

In the embodiment illustratedacup is employed having an open face-receiving side and comprising sections 6 and 7, that are slidably telescoped, said sections and cup tapering from the open side toward the opposite side, as clearly illustratedin Figs. 3 and 4. The inner section 6 carriesthe bot tom 8 of the cup and has contiguous to the furthermore provided with a depending outlet-nipple 10, provided with a closed lower end 11, and having an annular series of openings 12 therethrough. Communication between the interior of the nipple and the in- .teriorof the cup is established through an opening 13, controlled by an automatically and outwardly opening valve 14, located within the nipple. The openings 12 are arranged-to be covered by a sleeve 15, slidably fitted upon the nipple and having an inclined slot 16, through w 'ch passes a projection 17, carried by said nipple. It will thus be apparent that when the sleeve 15 is turnedit will move spirally upon the nipple and across the openings thereof.

The outer section 7 carries the top 18 of the cup, said top having an upstanding inlet-nipple 19, to which is attached the gas-conducting tube 20. The top, furthermore, is provided with a nose-receiving recess'21, opening from the open side of the cup and covered by a flexible cap 22, constructed of rubber or other suitable material, said cap being suitablysecured'upon the top 18.

Means are provided for holding the sections against relative movement, said means consisting of a clamp-bolt 23, carried by the outer section 7 and passing through a slot 24, formed in the inner section. The bolt has a head 25 at its inner end and a thumb-nut 26 threaded on its outer end. The head 25 is located within a cap element 27, secured to the inner sideof the inner section 6 and covering the slot 24. Suitable packing-strips 28, of rubber or other flexible material, are secured to the free upright margins of the sections and the bottomthereof at the open side of the cup. Head-straps 29 .of any desirable form are connected to stirrups 30, pivotallyjattached to the opposite sides of the outer section- 7.

inhaler, the sections are te escoped, as illustrated in Figs. 1 and'2, and the cup is applied to the face with the nose covered by the cap 22 and received in the recess 21, the bottom 8' fitting against the upper lip, which-is received in the recess 9. The inspiration of the patient raises the valve 14 and thereby closes the IOC opening 13, so that gas only received through the conduit 20 passes into the lungs. Upon the expiration the valve 14 drops. Consequently the respired air will pass through the.

outlet and through the openings 12. As this I outlet is located directly below the nostrils,

it will be apparent that the air will have a direct course between the two, and therefore there will be very little loss of the anesthetic agent. During the preliminary application of the device the openings 12 are left entirely open by moving the sleeve 15 downwardly; but as the patient becomes unconscious or is about anesthetized, so that deep breaths are no longer taken, the orifices are closed by turning the cap 15. Thus the gas is still forced through the nose into the lungs, while it cannot escape through the orifices.

If it is desired to administer the anesthetic through the mouth as well as through the nose, the cup is extended, as indicated in dotted lines in Fig. 2. The nose is still received within the cup 22 and in the recess 21, and the lower portion thereof is located below the mouth, or, in other words, the recess 9 receives the lower lip. The operation of the device, however, is substantially the same as that already described.

This structure has a number of important advantages. In the first place, by providing the inlet through the top the conduit maybe passed directly over the patients head, where it is out of the way of the operator. The outlet, as already described, is directly in line with the patients nostrils, so that the respired air has a direct passage thereto. The means for varying the size of this outlet is simple, can be adjusted with ease and expedition, and will maintain its adjusted relation. As already shown, the device is capable of use either as a nasal or an oral inhaler, and thus has particular advantages over the use of two separate devices. At the same time there are features which are useful in connection with either of these separate devices and entirely independent of the adj ustable or extensible feature of the cup.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. An inhaler including an extensible cup formed of substantially inflexible walls, and having an open rear side to receive a patients face, and edges which fit against the same.

2. An inhaler including an extensible cup comprising substantially inflexible walls, and provided with a rear open side to receive a patients face, said cup also having a valved air-outlet and a gas-inlet.

3. An inhaler including an extensible cup comprising relatively adjustable face-covering sections said inhaler being provided with a face-receiving opening located partially in each section.
